Apex unit 4 Exam Questions with Correct Answers The graph shown below expresses a radical function that can be written in the form f(x) = a(x + k)^1/n + c. What does the graph tell you about the value of c in this function - Answer-c is greater than zero The graph shown below expresses a radical function that can be written in the form f(x) = a(x + k)^1/n + c. What does the graph tell you about the value of a in this function - Answer-it is not possible to tell whether a is greater than or less than zero (wrong answer) a is greater than zero (wrong answer) The graph shown below expresses a radical function that can be written in the form f(x) = a(x + k)^1/n + c. What does the graph tell you about the value of n in this function - Answer-n is a positive even integer Which of the following are true statements? Check all that apply - Answer-The graph of f(x)=−1/2√x will look like the graph of f(x)=√x but will reflect it about the x-axis and shrink it vertically by a factor of 12. The graph of f(x)=−1/2√x has the same domain but a different range as f(x)=√x. (wrong answer) The graph shown below expresses a radical function that can be written in the form f(x) = a(x + k)^1/n + c. What does the graph tell you about the value of k in this function? - Answer-k is greater than zero which of the following would you do if you were to write the expression using an exponent: 3*3*3*3*3*3*3*3*3*3*3*3 - Answer-you would write 3^12 you would use 3 as the base and 12 as the exponent Which of the following could be the graph of f(x)=-a(x+b)^1/3 if both a and b are positive numbers? - Answer-(graph looks like an 2 on left side of graph) The graph shown below expresses a radical function that can be written in the form f(x)=a(x+k)^1/n+c. What does the attached graph tell you about the domain and the range of this function? - Answer-The domain is [-k,∞) & the range is (-∞,c] (wrong answer) The domain is (-∞,∞) & the range is (-∞,∞) Which of the following could be an example of a function with a range (-∞,a] and a domain [b, ∞) where a < 0 and b < 0? - Answer-i hate precalc if a^1/n=r then which of the following are true statements - Answer-r^n=a a^r=n (wrong answer) n^1/r=a n√
